Hair Follicle Drug Testing - Verona, NC

What it is, How it works

Hair analysis is now recognized as a valuable instrument for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers within the fibers of the emerging hair shaft. When collected near the scalp, hair can offer a detection window of up to roughly three months for alcohol and various drugs. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.

A sample size of 1.5 inches, approximately 200 hair strands (comparable to the width of a #2 pencil) near the scalp will provide 100mg of hair, the optimal amount for testing and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is suggested. If scalp hair is not available, a comparable quantity of body hair can be gathered. In reference to head hair, it pertains solely to scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).

Process Overview

The key procedures in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample within a laboratory's system. This process verifies that the sample was correctly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any other data entry not captured by an electronic chain of custody system.

Screening comprises an initial rapid test for commonly abused drugs. Although Screening offers a cost-efficient method to eliminate most samples for drug use, any positive findings need confirmation to be legally valid. Samples that indicate presumptive positive results in Screening require a further confirmation.

If a sample shows a presumptive positive during Screening, more hair is extracted from the original specimen and prepared for Extraction. Here, drugs are isolated from hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS methods. All samples indicating presumptive positives are cleansed before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and the compliance to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for as long as 90 days, unlike urine tests which offer a shorter detection timeframe.
• Challenging to falsify: It is highly challenging to alter a hair drug test, leading to more reliable results.
• Shows historical usage: It can illustrate a pattern of drug consumption over a timeframe, rather than just recent intake.

Limitations:

• Inability to detect recent intake: Detectability of drugs in hair takes roughly 5-7 days.
• Expense: Hair drug tests typically incur higher costs than other drug testing approaches.
• Outcome variability: Different elements such as hair color and personal differences in hair growth can impact the concentration of drug metabolites within the hair.

Note: Although frequently termed as "hair follicle tests", the test itself examines the hair strand, not the follicle beneath the scalp.
